IMPROVEMENT IN APPARATUS FOR HEATING.

Specification forming part of Letters Patent No. 178 3130, dated June13, 1876; application filed December 3, 1875.

To all whom it may concern:

Be it known that I, JOSEPH PEARSON GILL, of the city of Newark, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in an Apparatus for Heating and VentilatingPurposes; and I do hereby declare that the following is a full, clear,and exact description thereof, which will. enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accomin gs and public buildings, by the combination ofsuperheated steam at a high temperature with heated air in an apparatusor furnace having generators, superheaters, and distributing-chambersconnected by steam-pipes, said furnace being heated by hydrogen gas orother fuel, as hereinafter described.

The means employed by me are illustrated in the accompanying drawing,which is hereby made part of this specification.

Referring to the drawing, Figures 1, 2, 3, and 4 represent the furnacesheated in part by hydrogen gas and superheated steam. Fig. 1 is asection of the brick furnace across the front through D. Fig. 2 is alongitudinal section. .Fig. 3 is a cross-section of the iron furnace.Fig. 4 is a longitudinal section of the iron furnace.

These furnaces are provided with an airspace, O, surrounding the sidesand top, and extending several feet to the rear of them, as shown in thedrawing. Over the tire-place, and below the upper air-space, are aseries of pipes or tubes, M, for converting Water into steam, and thensuperheating the steam. The superheater is maintained at a red heat. Apipe, N, from the superheater M passes from the front to the rear of theupper air-chamber to heat the air therein. There are a number the warmair and prepare it to be breathed. Super-heated steam, of a temperatureof, for instance, 800 Fahrenheit, escaping into the heated air assistsin heating it and in a proper distribution of the heat, and at the sametime, on becoming cool,.gives the requisite degree of moisture to theair. The passage Q leading from the furnace being quite hot is made topass through the air-chamber 0, thus further assisting to warm the air,the products of combustion then passing through the pipe U to thechimney. The cold air from the exterior of the building is supplied tothe airchamber at the openings R, near the bottom of the sides of thefurnace, by means of the usual cold-air pipes, and the air is heated inthe four ways mentioned, viz: from the sides, rear, and top of thefurnace, by the superheated steam -pipe N, by the-superheated steamescaping through the small holes in the pipe N and commingling with theair, and by the passage Q. The temperature of the superheated steam isascertained by means of the pyrometer S.

.By means of this apparatus air properly warmed and moistened, anduninjured by being burned, can be delivered in quantity sufficient tothoroughly warm and ventilate buildings of any size or descrip ion.

Hydrogen. is admitted to the furnace by means of a pipe, V. Water isadmitted to the superheater M through the siphon-pipe W, which also actsas a safety-valve to the superheater. Water is let in to the siphon W bymeans of the valve X, or of an automatic arrangement, in such regulatedquantity as may be required for use.

In cases where a boiler is employed on the premises, the siphon 'W maybe dispensed with, and steam admitted directly into the superheater.

The hot air is distributed to the different apartments through theoutlet pipes or flues T. The fire-places of these furnaces and stovesare so constructed that in case of failure in the supply of, orinability to obtain, hydrogen or heating gas, the gas-pipes may beremoved,

and coal, coke, or other solid or liquid fuels may be used insteadthereof, or, when obtained, in combination therewith.

Referring to the drawings, similar letters in Figs. 1, 2, 3, and 4indicate similar parts.

A indicates the space answering to ashpit. B indicates the fire place. Vindicates the hydrogen pipe and burners. Q, indicates the flue fromfurnace. U indicates the pipe leading from flue t0 chimney. 0 indicatesthe air-chamber around the furnace and fine. M indicates thesuperheater. N indicates the pipes from superheater in upperair-chamber. S indicates the pyrometer. W indicates the siphon-pipe forsupplying the water to superheater. X indicates the valves regulatingthe supply of water to W. T indicates the flues conducting the hot airto the different apartmeuts.

What I claim, and desire to secure by Letters Patent, isa 1. The processof warming and ventilating dwellings and public buildings by admittingand diffusing superheated steam at a high temperature into atmosphericair heated in the air-chamber of a furnace, the steam being superheatedin a superheater or chamber in the furnace, separate and apart from theboiler or chamber in which the steam is generated, the two chambersbeing connected by a suitable pipe, and the superheated steam beingchamber or pipe, provided with fine perforations, substantially in themanner as herein described, and for the purpose set forth.

3. In an apparatus for heating and ventilating dwellings and publicbuildings, the combination of ash-pit space A, fire-place B, hydrogenpipe and burners V, flue Q, pipe U, air-chamber O, superheater M, pipeN, pyrometer S, siphon'pipe W, valve X, outlets 1, constructed,arranged, and adjusted substantially in the manner herein described, andfor the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.

JOSEPH PEARSON GILL.
